I don't know for a fact if I was actually caught. See, me and my boyfriend were in the family room in the back of the house on the couch. He was sitting and I was sitting on top of him facing away going at it. My dad was passed out drunk in the living room at the front of the house, and since he did this quite often I figured he wouldn't wake up. The only reason we didn't go in my room was it was right next door to where my dad was and my bed squeaked so I thought the couch was a better idea.
Well, halfway through our little session I saw my dad at the fridge. He wasn't facing me, but to get to the fridge he would have had to walk in facing us and we would have been clear to see. I jumped up and grabbed my boyfriend and hid by the computer where he could not see us. He went back in the other room and went to sleep and never said a word about it. It is possible he was still in a drunk haize and didn't look our direction, but I find that kind of hard to believe.
Needless to say I didn't do that when he was home anymore.
And I never caught my parents going at it. There were a couple mornings where when I went in their room to ask a question I got the distinct impression that they had just finished having sex. But I can pretend that wasn't the case... at least I don't have any visuals.
